A new geranylated coumarin, (E)-4-(1-hydroxypropyl)-5,7-dihydroxy-6-(3,7-dimethyl-2,6-octadienyl)-8-(3-methyl-1-oxobutyl)coumarin (named surangin D), was isolated from the bark of Mammea siamensis collected in Vietnam, along with four known coumarins, surangins B and C, and theraphins B and C, and seven xanthones, 1,7-dihydroxyxanthone, 7-hydroxy-1-methoxyxanthone, 1,7-dimethoxyxanthone, 1,7-dimet
一种新的香叶基香豆素,(E)-4-(1-羟丙基)-5,7-二羟基-6-(3,7-二甲基-2,6-辛二烯基)-8-(3-甲基-1-氧丁基)香豆素(命名为surangin D),是从越南采集的暹罗Mammea siamensis的树皮中分离出来的,还有四种已知的香豆素,surangins B和C,以及治疗素B和C,以及七个氧杂蒽酮,1,7-二羟基黄酮,7-羟基- 1-甲氧基x吨酮,1,7-二甲氧基x吨酮,1,7-二甲氧基-6-羟基x吨酮,1,6,7-三羟基x吨酮,1,3,7-三羟基x吨酮和1,7-二羟基-3-甲氧基x吨。通过光谱法(主要是1D-NMR和2D-NMR)以及甲基化衍生物的制备来确定它们的结构。测试了四种香豆素,surangins C和D以及Theraphins B和C在DLD-1(结肠癌),MCF-7(乳腺癌)中对细胞增殖的抑制作用,使用磺基罗丹明B(SRB)分析的HeLa(人类宫
